Cleaning the trackball
Tools: Paper, dry cloth or mild soapy water
Method:
For the stable performance of the system, you should perform periodical cleaning for
the trackball. A dumb cursor may be resulted from dirt inside the trackball.
a) Disassembling:
Rotate the trackball clamp ring 35 degrees anticlockwise. When the clamping ring
lifts, remove the clamping ring and trackball. You can draw out the ball with the
help of adhesive tape. See the figures below.
b) Cleaning:
Clean the lens slightly using the tissue until there is no foreign matter. Then clean
the other parts and the dust excluder. Make sure to exert force properly when
clean the small ball, otherwise, the small ball may drop down. See the figure
below.
No system shutdown is required during the whole clean. Reinstall the ball and
clamp ring after the clean is finished.
When liquid is spray onto the trackball area, most of the liquid can be discharged
through the waterspout, besides, you can dry the leaving water using the tissue
or cloth.
